To'aZZ whom it may concern Be it known that I, AUoUsT A. RUSTE- BERG, acitizen of the United States, and a resident of the city of Chicago, inthe county of Cook and State-of Illinois, have invented certain new andusefulImprovements in Hydrocarbon Generators and Burners; and I dohereby declare that'the following is a full, clear, and exactdescription of the same, reference being had to theaccompanyingdrawings, and to the numerals of reference marked thereon,which form a part of this specification.

This invention relates to an improved type of a hydrocarbon gasgenerating mechanism adapted for use in connection with stoves orfurnaces and embracing simultaneously acting primary and secondary gasacting to generate gas for use in the secondary burner, which in turnacts to generate anoil gas adaptable for use in furnaces or othersimilar devices.

It is an object of this invention to provide a gas generating oilburner, the gas nozzles of which are heated to prevent carbonization Kof the same.

It is also an object of this invention to construct a hydrocarbongenerator wherein a primary gas generator generates a gas adapted to beused as a fuel Ina secondary gas generator which heats nozzled oilcontainers whereby the oil therein is volatilized 9 I 9 f F andconverted into a fuel gas by carbureting air therewith.

Another object of this invention is the.

construction of a fuel gas generating device wherein a plurality of oilvolatlllzmg mechanisms are used to generate an oll-gas adaptable for useas a fuel in furnaces and stoves.

It is furthermore an object of this invention to provide a fuel. gasgenerating device wherein oi] fed into a primary generator isvolatilized. by a starting burner to prouce an oil-gas to be'burned in asecondary generator to heat oil fedthereto to volatilize said oil whichescapes through heated nozzles'and' mixes with air. to carburet' saidair to form a fuel gas producing a very hot flame adapted for use instoves, furnaces and other devices. An im ortant object of thisinvention is the pro uct-ion of a fuel gas generator wherein an oilwhich is volatilized' is permitted to escape through gas nozzles which,

during the process of gas generation. are

.with air,

1 view taken on line The hydro-carbon generator and burner embodying theprinciples of this invention s shown in Fig. 1, mounted upon a shelf 1,

of a framework 2, u on which-is mounted a furnace 3, of any esired typeadapted to be heated by means of a generator gas. Secured upon the shelf1, are end frame bases or standards 4, spaced opposite one another 7 isan enlarged" fragmentary detail and provided with an integral support orshelf 5, upon which is securely seated a storage tank or primary gasreservoir 6, hav-' ing integrally formed or rigidly secured to thebottom thereof a fuel mixing or carbureting pipe 7, one end of whichcommunicates with the interior of the storage tank 6, and the other endof which is open, and disposed opposite the inner surface of the endwall of one of the end frames 4. The front wall of the storage tank 6,is provided with a plurality of alined apertures or openings 8, toafford a primary generating burner.- Projecting through a suitableaperture in the end wall of one of the end frames 4, and removablythreaded into one end of the storage tank6, is an arm 9, to the outerend of which is rigidly secured an inclined pipe or auxiliary generatingburner 10, provided with a plurality of burner apertures 11, in thelower surface thereof.

Disposed longitudinally in front of the apertures 8, of the primaryburner, and with the ends thereof projecting through and sup I ported bythe end frames 4, is a main or primary oil-gas generating tube or pipe12, having a-- spiral spring or coil 13, disposed therein. Removablythreaded into one end of the main generatlng pipe 12, is one end of anoil control valve 14, the other end of which is connected to an oil feedpipe 15, which is attached to a primary oil supply pressure tank 16,disposed to one side of the framework 2, or in any other convenientplace. Mounted longitudinally of the storage tank 6, and directly belowthe main; generating pipe 12, is a wick starting burner 18.

Removably threaded into the other end of the main generatin pipe 12,.isa stub connecting arm 19, wlnch projects through a suitable openingprovided for the purpose in one of the end frames 4, and has integrallyformed at right angles on the outer end thereof, an inclined auxiliarygenerating pipe or superheater 20, which is closed at its upper end andopen at its lower end. The lower open end of the generating pipe 20, isclosed by means of a stopper or plug 21,- removably threaded into theopenend of said generating pipe to permit cleaning thereof. Asclearlyshown in Figs. 3 and 14, the inclined generating pipe 20, isdisposed below the inclined auxiliary burner 10, and is parallel theretoto permit the flames issuing fromthe apertures 11, to heat said inclinedgenerating pipe, as hereinafter more fully described.

Integrally formed at right angles near the lower end of the inclinedgenerating pipe, and parallel to and below the stub arm 19, is a shortnozzle pipe 22, having a small passage 23, therein. which continues onthrough the generating pipe 20, communicating with a passage 24, in saidgeninclined generating pipe 20, near the lower end thereof and oppositeto the nozzle pipe 22. Adjustably threaded in the enlarged.

passage of the pipe extension 26, is a threaded shank or screw 27 havinginte-- grally formed on one end thereof a valve rod 28, of reduceddiameter alfording an inclined or tapered portion 29 between said shankand valve rod, adapted to engage in the seat 25. The valve rod 28,projects longitudinally through the passage 23, and has its outer endtapered, as denoted by the numeral '30, to permit the same to seat orproject into a tapered oil-gas outlet passage formed in a valve plug 31,removably threaded into the outer end of the short nozzle pipe 22,thereby affording a suitable oil-gas outlet nozzle which is positionedwith the end thereof axially alined and opposite to the open end of thecarbureting pipe 7, as shown in Fig. 4. The outer end of the pipeextension 26, is provided with an enlarged chamber in which. is seated asuitable packing 32, disposed around a valve stem or rod 33, integrallyformed on the other end of the shank 27. Said valve stem 33, projectsoutwardly through a cap 34, re movably threaded upon the outer end .ofthe pipe extension 26, for holding the packing 32, in position. Theouter end of the valve stem 33, is of rectangular cross-section toafford a means for readily adjustmg the oil-gas inlet valve mechanism.

Integrally formed at each end of the top 'wall of the storage. tank 6,is a socket 35,

having an opening 36, therein. A secondary burner is removably securedin each of the sockets 35, and comprises a stand or feed pipe-37, thelower end of which is adapted to rotatably and removably fit into one ofthe sockets 35, over the opening 36, therein. Formed integrally on theupper end of each feed pipe 37, is an apertured bottom or base plate 38,having a peripheral notch or groove therein to permit 'a burner casing39, to seat upon said base plate. Pivotally mounted upon each of thebaseplates 38, to form a valve, is a-shutter or a regulating orcontrolling disk 40, provided with a handle 41, which extendsoutwardlythrough a suitable slot in the burner casings, to afford a means forswinging the disk 40, to regulate the flow of oil-gas from the storagetank 6, into the burner casings. Projecting outwardly burner tubes 42,is a secondary oil-gas'generating pipeor tube 44 provided with an oil.inlet control valve 45, on its inner end. The outer end of each of thegenerating tubes 44,

curved baffle plate or hood 48. Suitable sup-5 ply or feed pipes 49,connect the inlet control valves 45, with a secondary oil supplypressure tank or reservoir 50, mounted to one side of the framework 2,or in-any other suitable position. sides of the furnace 3, arecarbureting or flue pipes 51, the upper ends of which are horizontal andproject into suitable apertures or passages, 52, formed in the furnacewall. The other endof each of the flue pi cs 51, is bent downwardly andis positione a short distance from and directly above the outlet openingin one of the oil-gas tips 47, as clearly shown in Fig. 1. A baffleplate or block 53,- is positioned Within the furnace 3, opposite theinner ends of the passages 52, to afford an obstruction whereby flames.entering the furnace are deflected upwardly into the heating chamber ofthe furnace.

The operation is as follows:

To start the device, kerosene or any other suitable hydro-carbon fuel issupplied from the primary pressure tank 16, through the pipe 15, intothe primary generating pipe 12, the valve 14, 'of course, being open.The wick of the starting burner 18, is saturated with alcohol andlighted, the heat therefrom tending to rapidly heat the primarygenerating pipe 12, and the spring 18, therem, thus causing a primaryvolatilization of the oil within the said generating-pipe to form anoil-gas, which passes through the inclined generating pipe 20, into thepassage 23, of the nozzle, the end of which is disposed opposite the airintake or open end of the carbureting pipe 7. By turnin the valve stem33, the tapered end 30, of tiie valve rod 28, is unseated, thuspermitting the oil-gas to pass through the restricted outlet passageinto the carbureting pipe 7, to be mixed with air which is drawn intothe open end of said carbureting pipe; The carbureted air thus forms asuitable fuel gas which passes upwardly into the storage tank or 'casing6, the shutters 40, being in closed position, to prevent escape of theoil-gas into the secondary burners. r

The oil-gas thus generated and flowing into the storage tank 6, passesoutwardlythrough -the apertures 8, forming the primary burner, and alsopasses into the inclined auxiliary burner 10, and out through Disposedon opposite the burner apertures 11, thereof. The oilgas thus escapingthrough the apertures 8 and 11, is ignited, the resulting flames fromthe apertures 8 and 11, striking or passing around the respectiveprimary generating pipe-v 12, and the inclined generating pipe 20, andthe 'oil-gas' nozzle mechanisms, thereby volatilizing thekerosenepassing into the main generating pipe 12, and the inclined generatingpipe 20, to generate more gas by the burning of oil-gas alreadygenerated, thus permitting the process of oil-gas generation tocontinue, after being started by the starting burner which, of course,goes out after the alcohol with which the wick was saturated has beenburned up.

After the device has been started as described, the shutter valves 40,are opened, permitting the oil-gas from the storage tank 6, to flow intothe casings 39, of the secondary burners, and then into the'burner tubes42, and out through the openings 43. The escaping gas is, of course,lighted, the flames passing upwardly around the secondary oilgasgenerating pipes 44, and also around the elbows 46, striking the inneror under surfaces of the hoods 48, thus also heating the same and thegas tips 47. By opening the control valves 45, kerosene or othersuitable oil is admitted from the pressure tank 50, into the heatedgenerating pipes 44, and

is volatilized to forma gas which passes upwardly through the restrictedoutlet openings in-thefastips 47, and into the .flue pipes 51, an ismixed with air drawn into the lower open ends of said flue pipes. Theoil-gas thus generated, 'flows into the furnace 3, through the passages52, and is ignited. The flames produced thereby strike against thebaflie block 53, and are deflected upwardly into the main heatingchamber of thefu-rnace. Dueto the novel arrangement of the oil-gasgenerating mechanisms, the gas generated therein is heated during itsentire passage through said mechanisms, and is not allowed to cool offbefore it is mixed with air. -This construction prevents carbonizationof the gas nozzles and gas tips,.which are thus kept clean and free fromclogging. If, however, any foreign substances contained in the keroseneoilare deposited in the nozzle or in .the secondary gas generatingmecha-.

range without departing from the principles of this invention, and Itherefore do not desire to limit the patent granted otherwise thannecessitated by the prior art.
